Kernel dmesg output after boot
Hello,
Since my upgrade to Kubuntu 15.04, I have had multiple freezes due to the
nouveau driver. Most of them happen when I am away from my computer, once the
screen is locked. I disabled the screen switch off feature, but kept the dim
screen after 15 minutes feature. I do not have any suspend or hibernate
features enabled. I still get the freezes.
When the freeze occurs, whatever was on the screen is frozen (so I can see the
time at which the freeze occured). My keyboard and mouse are unresponsive
(numlock led doesn't turn on/off). I can remote in (ssh) to my computer and
restart X and everything works correctly.
I do get some nouveau errors in dmesg, though it seems to be after I restart X.
See below the Xorg.0.log backtrace.
I am using the nouveau driver v1.0.11 with Xorg v7.7 (with ubuntu patches).
